Will this inverter run a CPAP without the humidifier for 8 hours on a good 12 volt deep cycle battery? Do I need an AGM deep cycle battery?

That will depend on the Ah use age of your machine And the size Ah of your battery the inverter will run the machine if the battery is large enough

For indoor use definately get an AGM deep cycle battery (Amazon has Optima blue top deep cycle battery). Less chance that it will vent toxic gas than a lead acid deep cycle battery.

Yes. I can go 3 nights using my CPAP with a DC cord so I don't need the AC inverter option. You can still get a full night on the inverter if you don't have the DC Adapter. As with all CPAP its recommend to not used the humidifier option when on battery power. So I own two of these to handle week long camps.

Yes, but be aware of another potential problem. You are not supposed to use the humidifier while on battery power, to conserve energy. When, on a vacation in Turkey, I tried to use the system, I couldn't figure out how to attach the breathing tube directly to the CPAP unit. This was on a boat that lacked electric power. Turns out my tube was "electrified" in some way, and was not compatible with the battery system. Now I have an non-electrified tube. I have not had occasion to use the battery with the new tube yet, but I trust it will work. Moral of the story: test your equipment thoroughly before you go to Turkey.

Most CPAPs have a DC input so you don't have to deal with the inefficiency of using an inverter and then the additional losses due to the CPAP converting it back to 12 VDC.A typical CPAP will draw about 12 watts.

Hello, A C-pap machine is used to help you breath while you sleep. To operate it remotely, as in overnight camping or similar activity, you would want to figure out an average 8 hour night's sleep power requirement for the C-pap machine. In this example, IF your C-papa machine operates at 100 watts, the EL2601 inverter would be more than ample. The battery that you would want to have already, fully charged, would be a large deep cycle battery. Double check the exact power requirements from the manufacturer's contact section of their business.

7500 mAH will not keep a CPAP running all night, but it might let you ride through smaller (maybe 30-90 minutes, depending on your machine) outages - if it lets you charge it and take output at the same time. A battery to run a CPAP all night is much bigger (I have one that is 44,000 mAH).

Does this inverter slowly drain the 12V battery with no load (eg, appliance, such as a water well pump that only runs for few minutes when water pressure is slow, connected to it, but not running)?

It depends on how long you intend to run the appliance. Frig. 3-4amps @ 120V = 420 watts. Divide by 12 = 35amps per hour. Typical large battery has 150 amp hour capacity but not at that rate and not fully discharging. Regular batteries are cheaper and you will only discharge to about 11.5 volts. That is why most residential system use line inverters and sell back to the utility. My starting point would be 10 if I was seriously wanting to benefit from a generator / battery backup on these appliances.. A couple of batteries could take all the charge a 100 watt panel could produce for days. Store it, use it or lose it because you can't afford your design intentions here.

115-230 VAC is a selection, not a range. So if you select 115 VAC then you have selected the correct output for this inverter as it is a nominal 120 VAC inverter. With a range between 7.5 amps and 15 amps being drawn by the compressor, the inverter is just a bit shy of what you require. Another big problem will be the stoutness of the battery you are using. From a static 12 VDC source (stand alone battery), converting it to 120 VAC, drawing 15 amps, the power used would be 1,800 watts. That is a little past the rated 1,500 watts, but not beyond the momentary peak of 3,000 watts. From an active 14.5 VDC source (a 12 Volt battery driven by a alternator), converting it to 120 VAC and drawing 15 amps, the power used would be 1,740 watts. Again, that is a little past the rated 1,500 watts, but not beyond the momentary peak of 3,000 watts. But here is the catch, an AC inverter is never 100% efficient, so the calculations stated above are actually worse. Could be 20% off or more 'off' due to inefficiency. Technically, you could run your compressor for a few moments without damage to the inverter, but this inverter would not be the proper selection for your work load. I would select something in the 2,400 watt range for the continuous power required that you seek. This would give you 20 amps minus 20% inefficiency giving you 16 amps of reliable current. So 2,500 watts, with the ability to surge to 5,000 watts momentarily (allowing a 100% overage of current drawn on start up for the motor of the compressor) should fit your bill. All units will be very happy with each other (provided you have a robust battery, or battery bank). An "8D" battery would serve you well (but pretty heavy at 161 lbs each). Do not forget "voltage drop" that happens, and make sure you use HEAVY cables to the battery; perhaps 2/0 pure copper (not copper clad) cables. This will keep your input high. It is worth the expense (and you only buy them once).

We use this for our marching band to power the base amp. To answer your question, the battery is rated at 396 watt hours. So a full charged battery should give you at least 300 watt hours from thru ac inverter (120V). Your CPAP machine as described would need 240 watts for the 8 hour duration.

specs for the unit say .6A no load (standby) current draw so eventually it would pull battery dead if you did not have any charging on your battery bank, probably not a bad idea if leaving un-attended for long periods to have a battery disconnect for the inverter so you don't have some glitch that would allow inverter to possibly short and start a fire.

That's a great battery for an inverter, but I wouldn't go any larger on the inverter with that size battery. Just watch your usage and time so that you don't run the battery all the way down.

My Goal Zero Escape 150 (same capacity as this one) runs my CPAP for 4-5 hours, but not all night. This unit only stores about 14 amp hours. You have to determine your amp hour needs. Watts/Volts = Amp Hours. Find out the wattage your device requires then divide by 12 volts and see how many amps it will draw... then purchase a unit that will power your projector as long as you need it to via amp hours. :)

It would run it for about 18 minutes if fully charged. The inverter has the power and if you have enough battery it will run fine.

We connect to a deep cycle marine battery, which then runs things requiring 12 volts--whether that is enough for you depends on your uses. It is enough to keep the battery charged for our relatively light usage (no floodlights, loudspeakers, heaters). It requires a cord with a cigarette plug to plug in the inverter.

The battery in packs like this have a rating like "18 amp-hour" hinting it can supply 1 amp (at 12V) for 18 hours, or 2 amps for 9 hours, etc. Running the inverter will use a bit of energy itself, otherwise it just transforms the power to 120V where something needing 1 amp at 120V needs 10 amps at 12V (since both of those =120watts). I don't know exactly what your blue ray player or such uses, so the only way to know for sure is to measure them in use with something like the "kill-a-watt" meter. I doubt they need much energy, so if it's under 1 amp at 120V the battery should last at least 2 hours, but that's a guess.

Yes, we are using this battery for continuous power on a CPAP. The battery is on a trickle charger, and the CPAP is directly connected to the 12VDC.
